Long-term results of laryngotracheal resection for benign stenosis from a series of 109 consecutive patients

Abstract

Objectives: Long-term results of patients undergoing laryngotracheal resection for benign stenosis are reported. This is the largest series ever published.

Methods: Between 1991 and March 2015, 109 consecutive patients (64 males, 45 females; mean age 39 ± 10.9 years) underwent laryngotracheal resection for subglottic postintubation (93) or idiopathic (16) stenosis. Preoperative procedures included tracheostomy in 35 patients, laser in 17 and laser plus stenting in 18. The upper limit of the stenosis ranged between actual involvement of the vocal cords and 1.5 cm from the glottis. Airway resection length ranged between 1.5 and 6 cm (mean 3.4 ± 0.8 cm) and it was over 4.5 cm in 14 patients. Laryngotracheal release was performed in 9 patients (suprahyoid in 7, pericardial in 1 and suprahyoid + pericardial in 1).

Results: There was no perioperative mortality. Ninety-nine patients (90.8%) had excellent or good early results. Ten patients (9.2%) experienced complications including restenosis in 8, dehiscence in 1 and glottic oedema requiring tracheostomy in 1. Restenosis was treated in all 8 patients with endoscopic procedures (5 laser, 2 laser + stent, 1 mechanical dilatation). The patient with anastomotic dehiscence required temporary tracheostomy closed after 1 year with no sequelae. One patient presenting postoperative glottic oedema underwent permanent tracheostomy. Minor complications occurred in 4 patients (3 wound infections, 1 atrial fibrillation). Definitive excellent or good results were achieved in 94.5% of patients. Twenty-eight post-coma patients with neuropsychiatric disorders showed no increased complication and failure rate.

Conclusions: Laryngotracheal resection is the definitive curative treatment for subglottic stenosis allowing very high success rate at long term. Early complications can be managed by endoscopic procedures achieving excellent and stable results over time.
